Active cavity radiometer (acr) sensors have demonstrated their state-of-the-art accuracy and precision for solar observations in space flight applications as the sensors of the active cavity radiometer irradiance monitor experiment on the solar maximum mission. the design and operational advantages… More

Radiometric Corporation proposes to apply a new microwave technology to profiling of atmospheric water vapor. Water vapor is the most significant and most highly variable of greenhouse gases. It is also the most significant and highly variable atmospheric constituent in the formation of weather… More

40118 November 8, 1996 MMIC Technologies Water vapor is the most significant of greenhouse gases. It also is the most significant and highly variable atmospheric constituent in the formation of weather and the transfer of atmospheric heat. Yet, it… More

It is known that atmospheric observations by microwave radiometers can predict and measure satellite link losses. These instruments, however, have historically been costly, bulky, and somewhat fragile, and therefore not desirable for monitoring satellite link conditions. Radiometries is proposing… More

We propose to test a new method for remote passive detection of hydrometeors (cloud liquid water droplets, drizzle, rain, hail, and snow) from an aircraft. The method uses an advanced radiometer to measure differences between horizontal and vertical polarization of microwave radiation. The… More

New developments in atmospheric sensing and modeling present the opportunity for significant advancements in local weather modeling and forecasting. New sensors include wind radar, microwave profiler and GPS networks. These sensors provide continuous wind,temperature and humidity measurements. We… More

In Phase I we demonstrated that tropospheric wind, temperature, humidity and cloud liquid profiles can improve local weather forecasting. We propose in Phase II to develop "Nowcaster Plus", a turnkey local weather forecast system using local troposphericprofile and regional GPS data to significantly… More

70084 Current microwave radiometer designs are inadequate for measuring low atmospheric water vapor concentrations crucial to global climate research. This project will develop a new design that will provide reliable and accurate measurements of low water vapor concentration and will also… More

70084S02-II Current microwave radiometer designs are not suitable for measuring low concentrations of atmospheric water vapor, information needed for climate and radiative flux research at high latitudes and in arid regions. This project will develop an inexpensive, high performance, modular,… More

Aircraft icing continues to be one of the major safety and operational concerns of the FAA, elements of the military, and the foreign military and civilian counterparts. Attempts to develop methods to directly detect aircraft icing meteorological conditions have met with mixed success. Combining… More
